Intellisense can't deduce operator* #6814
Description
Issue Type: Bug
Intellisense reports that 'more than one operator "*" matches these operands [...]' with:
template<size_t rows, size_t cols, typename Int = int>
class Matrix {
...
public:
template<typename _Int> Matrix operator*(const _Int& rhs) const { ... }
template<size_t _Cols, typename _Int>
Matrix<rows, _Cols, Int> operator*(const Matrix<cols, _Cols, _Int>& rhs) const { ... }
...
};
template<size_t, size_t cols, typename Int, typename _Int>
Matrix<rows, cols, Int> operator* (_Int lhs, const Matrix<rows, cols, Int>& rhs) { ... }when I do:
auto matrix3 = matrix1 * matrix2;Even though code compiles fine under x86_64-w64-mingw32-g++-win32/posix 8.3; this is the same on both insiders and normal release, and occurs the same using standards 11 through 20. It's not the worst thing, but it is annoying.

Thanks for reporting this. I've filed an internal bug against our parser shared with VS. The bug only repros in "gcc" mode, so one potential workaround would be to set your compilerPath to a clang++ compiler instead (to use clang mode).

Thank you for the report. We’re closing this as not planned.
This issue has been inactive for a long time and if the VS bug filed has not been fixed yet, it is likely that we won't be getting a fix in VS Code any time soon.
